Well it was bound to happen sometime, I have ick in my display tank. Seen it on a few of my clowns and some of the acara. I've had it before and treated it successfully with heat alone. So that's the route I'm going, the temp is already up to 86 and I will keep it between that and 88. All my fish are good for that heat. Not sure about adding salt since this is a planted tank. So far looks like one of my largest clowns won't make it.
